The median is the value with the same number of data points below it as above it. If the distribution has an odd number of data points (as this one does) then the median will be one of the data points.

Here 4 has 4 data values below it, and 4 data values above it.

The median is 4.

(2) The mode is the data value(s) that occur the most often (and at least twice.)
